SILO.

Application filed April 28, 1915.

To all whom it may concern Be it known that I, AUeUs'r T. BRAMER, a citizen of the United States, residing at Monett, in the county of Barry and State of Missouri, have invented certain new and useful Improvements in Silos, of which the following is a specification.

My invention relates to improvements in silos of the knock-down type.

An important object of the invention is to provide a silo of the above mentioned character, so constructed that its holding capacity may be varied by adding or taking away a horizontal layer or layers of casing-sections.

A further object of the invention is to provide a knock-down silo, the parts of which are so constructed that they may be arranged in a compact manner for shipment a lid conveniently assembled in erecting the s1 0.

A further object of the invention is to provide a silo of the above mentioned character, which is simple in construction, inexpensive to manufacture, strong, durable, and damp or air-proof to a high degree.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same, Figure 1 is a front side elevation of a silo embodying my invention, one-half thereof being shown in central vertical section, Fig. 2 is a perspective view of one of the detachablewall sections, Fig. 3 is a horizontal sectional view taken on line 33 of Fig. 1, Fig. 4 is an enlarged detail section through the means for connecting the upper and lower edges of two of the wall sections, and, Fig. 5 is a central vertical sectional view through the top of the silo.

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 10 designates a preferably circular base formed of concrete or the like upon which the silo is preferably mounted. Arranged upon the base 10 is an anchor ring 11, secured thereto by bolts 12 or the like. Rigidly secured to the top of the anchor ring 12 is a locking ring 13, provided with an outer upstanding annular tongue or flange 14, as shown.

The body portion or casing of the silo is preferably cylindrical and is formed in a plurality of casing-sections 15, arranged to break joint, as the bricks of a wall. Each casing-section comprises a rectangular frame Specification of Letters Patent.

including horizontal curved beams 16 and 17 rigidly connected by end vertical beams 18 and 19 and intermediate vertical beams or studs 18, as shown. The upper beam 16 is provided with an outer upstanding curved tongue or flange 20 while the lower beam 17 is provided with an inner depending curved tongue or flange 21. The vertical beam 18 is provided with an inner tongue or flange 22 and the vertical beam 19 is provided with an outer tongue or flange 23, as shown. Each. casing-section 15 has preferably cypress sheathing boards 24 and 25 arranged upon the inner side thereof and secured or nailed to the vertical beams 18, 18 and 19. These boards 24 and 25 break joint and a section of water-proof paper 26 is arranged between the two layers of sheathing boards, providing a construction which is highly damp or air-proof. These casing-sections may be formed in suitable sizes depending upon the desired size of the silo. I have found that satisfactory results are obtainable by forming the casing-sections 15 of such a length that ix of them arranged in end to end relation, when assembled, produce a circular wall or body of the silo. The lowermost layer of casing-sections 15 engage the locking ring 13, with'the tongues 21 arranged inwardly of the tongue 14 and interlocking therewith. The vertical tongue 22 of one casing-section 15 is arranged inwardly of the vertical tongue 23 of the adjacent casing-section and interlock therewith.

The numeral 27 designates a continuous locking ring, which is preferably formed in upper and lower annular sections 28 and 29, secured together by any suitable means, each section being formed in any suitable number of rigidly connected parts as may be found advantageous. The upper section 28 is provided with an outer upstanding annular tongue or flange 30, while the lower section 29 carries an inner depending annular tongue or flange 31. The locking ring 27 is arranged upon the top of each horizontal layer of casing sections and its depending tongue 31 is arranged inwardly of and interlocks with the upstanding tongues 20 while the upper tongue 30 is arranged outwardly of and interlocks with the tongues 21 carried by the bottoms of the next upper horizontal layer of casing sections 15. It is obvious that the locking ring 27 has detachable engagement with the top and bottom of the adjacent horizontal layers of casingsections 15 and securely bind them together.

' A locking ring 27 is interposed between thetop and bottom of the upwardly succeeding horizontal layers of casing-sections, as is ob Vious.

A locking ring 27 is arranged upon the top of the uppermost horizontal layer of easing sections 15 and is adapted to have interlocking engagement with a ring 32, having an inner depending tongue or flange 33,

arranged inwardly of the tongue or flange 30. The ring 32 is included in a conical roof or top, and boards or planks 84 are nailed or otherwise secured thereto and are also secured to a suitable number of rings 35 arranged inwardly thereof. The roof is tapered and decreases in diameter upwardly and is provided at its reduced upper end with an air outlet opening 35, covered by a cap or cowl 36, secured thereto by spaced legs 37, as shown.

Certain of the casing sections 15 are provided with door openings 38, occurring between two of the vertical beams 18', with the sheathing boards 24: and 25, cut away for providing the opening. These openings are covered by doors 39,opening inwardly and held in place by a latch or latches 40, as

shown. The doors 39 are preferably arranged in a vertical row, as shown.

If found advantageous the ends of the casing sections may be connected by bolts 38. When the caslng-sectlons are assembled, weather-boards 89 or the like may be secured to the outer sides thereof, but I have found that these weather-boards may often be dispensed with. V i

It is obvious that I have provided a silo formed in sections which may be readily separated and assembled. When it. is desired to increase the capacity of the silo the roof is'raised and one or more horizontal layers of casing-sections 15 added thereto, subsequently to which the roof is again arranged upon the uppermost layer.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit "of the invention or the scope of the sub joined claims.

Having thus described the invention, I claim 1. A wooden knock-down silo; comprising a lower unit consisting of detachable casing-sections,provided at their tops with upstanding flanges starting at the outer sides thereof and extending toward their inner sides and terminating near and spaced a substantial distance from such inner sides to provide. an interior recess, an upper unit consisting of detachable casing-sections, provided at their bottoms with depending flanges starting at their inner sides and exspaced a substantial distance from the inner side, the flanges of the locking ring interfittlng with the flanges of the upper and lower casing-sections.

2. A wooden knock-down silo; comprising a lower unit consisting of detachable casing-sections, provided at their tops with upstanding flanges starting at the outer sides thereof and extending toward their a substantial distance from such inner sides to provide an interior recess; an upper unit consisting of detachable casing-sections, provided at their bottoms with depending inner sides and terminating near and spaced flanges starting at their inner sides and extending toward their outer sides and terminating near and spaced a substantial distance from such outer sides to provide an exterior recess; and a continuous locking ring arranged between the lower and upper units, comprising lower and upper strips which are secured together, the lower strip being provided upon its bottom with a depending flange starting at the inner side thereof and extending toward its outer side and terminating near and spaced a substantial dlstance from such outer side, and the upper strip being provided with an upstanding flange starting at the outer side tial distance from such inner side, the flanges of the locking ring interfitting with the flanges of the upper and lower casingsections.

3. A wooden knock-down silo; comprising alower unit consisting of detachable casing-sections, each casing-section being provided at its top with an upstanding flange arranged near its outer side and spaced a substantial distance from its inner side, and sheathing boards secured to the mner side of each casing-section and extend- ,ing upwardly beyond the upper end thereof to cooperate with the flange for providing a recess having its sides closed; an upper vunitconsisting of detachable casing-sections,

each easing-section being provided at its bottom with a depending-flange arranged near its inner side and spaced a substantial distance from its outer side, and sheathing thereof-and extending toward its inner side and terminating near and spaced a substanboards secured to the inner side of each cas ing-section and extending downwardly below the same for a substantial distance; and a continuous locking ring provided at its bottom with a depending flange arranged near its inner side and spaced a substantial distance from its outer side, and at its top with an upstanding flange arranged near its outer side and spaced a substantial distance from its inner side, the flanges of the locking ring interfitting With the flanges of the casing-sections and the ends of the sheathing boards overlapping the locking rim.

4 A Wooden knock-down silo, comprising a lower unit of detachable casing-sections provided at their tops With upstanding flanges forming in effect a continuous flange, an upper unit of detachable casingsections having depending flanges forming in effect a continuous flange and disposed in a different plane from the flanges of the lower casing-sections, and a locking ring having depending and upstanding flanges disposed in different planes and adapted to interfit with the flanges of said casing-sections.
